@z4096tri1: Same glitch, Windows 7 IE9. Allowed me to continually level.
Frozen on the spot with level up window, after I allocate the stat points there's a weird beeping/clicking noise. Meanwhile HP bar takes some damage (about 75%) and my XP raises, full in about 3 seconds flat. Seems to be an endless loop. Well at least got some highscores out of it.
If there's no good players to recruit at the end of the season, exit to the main menu and then continue season. The recruit list will refresh with new players.
